Defeating pDriLl´s Crypto keygenmes

Days ago I come across some nice crypto keygenmes by pDriLl. so far I´d seen 3 of them, but AFAIK there are four total. I´m missing the first one... so if someone have it point me please where it is... And I´m still working on the 4th keygenme...

Thanks to drizz for his miracl header for MASM :)

Have a nice day everyone!

PS: DAMN, HOW FUGLY LOOKS THIS F*CKING TEMPLATE FFS!

Reversing/Keygenning Tutorials

Well after talking with b_W (or whatever nick he had changed to now...) about a tutorial for "newbies" about keygenning I told him I will make at least two just to help him, and here they are!

Working on the AWESOME keygen for Keygenme#3

In these two first tutorial you will see how I analize and reverse a crackme, EasyCrack by Kwazy Webbit, in the first one, and Keygenme#3 by Enforcer in the second place.

Requeriments:

- Basic knowledge of programming, assembly language, debugger use (OllyDbg mainly.)

Aims:

Working on the keygen for Kwazy EasyCrack

- Show the workflow of a common reversing/keygening session. The use of tools and analizys and understanding of code and algorithms

Reversing Keygenme#3

What it's NOT:

- It's not a tutorial about assembly language, neither about specific tools. It's not theory. If you want to indeep into some topics you should follow mentioned references.

Tools:

- OllyDbg [site][standalone - version 1.10][modified version 1.10][full package][full + tools * list of tools] (not yet, sorry)

- WinAsm [site][installer][portable], MASM32 package [site][installer][full package]

Reversing EasyCrack

System requeriments:

- Flash v6.0 or above [site][SWF player]

- 256MB memory at least

PS: A day after established release date. Well done! Never such a punctual before!

Asphyxia´s km#6

blah blah blah, my km #6 and goin boring again. nothing to see here, but if u have some spare time then u've this crappy thing...

mmm.. i've to say that the main "protection" algo wasnt my idea, i'd seen it somewhere and then coded it. its pretty easy to solve and make a kg is easier

rate 0/5 ;_;

chill the fuck out

Asphyxia's km#5

Well there is my #5 keygenme. There is (still) nothing interesting. I thought a lot of things but finally i just get bored and code this little boring thing. Maybe the next one will bring something cool, but till then u have this crap.

WHAT A BORING DAY!!

Mental Alteration Recruit 2009

Its wasnt to hard neither take too much. In fact few days after finished my km#4 i came with this recruit. After some problems that almost burn up all my work i can publish it.

Way too much gfx for the year to me ¬_¬ Nice witch anyways. Its a layered window translucid with SetLayeredWindowAttribute, but i directly import it so i hope it'll be runned only on xp or vista boxes.

The only good thing with the gfx is it frame and buttons, and i didnt do it. Its was a work of Mynes//FOFF. Nice work, thx for sharing XP

I wasnt in any moment sure about the gfx; i choose it cuz of the mod; Some dark, some EBM, some shit like that.

Finally the scroller is an adapted version of the nfo viewer i'd wroted some time ago.


Thats enough gfx. The rest of the km (about 10% of its size) is the real meaning of it.

There are some nasty stuff to piss off crackers XD that'll fuck some newbs.

The recruit is mainly a sum of some works into vx. But the main core its the same crypto shit i usually use.

I tried hard to make it all stable i can but it can have some problems here and there. Unfortunally.

Thats enough, enjoy it if u can.

Enough words!!,

Defeating a nice series

Prof. DrAcuLA had done a nice km series; pretty nice to whom´re learning keygenning... some buggy and not soo crypto... but anyways nice...

Cryptok KeygenMe {1} by Prof. DrAcULA

Ok, the first of the series gives to crackers a cast-128(encryption), and base64(encoding) algos to beat. Pretty hard to newbies but not hard at all.
There is also a crappy bug.

download

Cryptok KeygenMe {2} by Prof. DrAcULA

This one give us two challenges: make a keygen and a loader. First challenge put us infront of crc32, and sha256 (hash); second challenge is to show in a dialog a bitmap. I didnt solve the 2nd cuz i dont know how to... :(... anyway nice one.

download

Cryptok KeygenMe {3} by Prof. DrAcULA

Third one looks pretty nice but it has a serious bug and cannot be keygenned... MD5, bignums, crc16.

download

Cryptok KeygenMe {4} by Prof. DrAcULA

Last one is keyfile-based and is very easy. crc32.

KeyGenMe #2 by Enforcer/ARTeam

An easy and nice crackme by Enforcer. I didnt finish the tuto/notes but its pretty easy to keygen...

download

Asphyxia´s km#4

A nice km to play with crypto crap. I think may u'll like it if u are learning crypto or u are an entusiast of cryptos.
